American Indians are the most under-represented minority group across all levels of education. The present study investigates sociocultural, psychological, and nontraditional academic factors that influence American Indian students’ decisions to pursue higher education (e.g., vocational training, college). Nineteen American Indians with previous academic difficulties completed several self-repo...

BACKGROUND Leisure-time sitting-time (LTST) is seen as a possible independent risk-factor for physical and mental health, but research on psychological determinants is sparse. Associations between sitting-time and the personality dimensions of neuroticism, extroversion, openness, agreeableness, and conscientiousness, and the role of general self-efficacy (GSE) were investigated. METHODS A pop...

Mental abacus (MA) is a technique for performing fast, accurate arithmetic using a mental image of an abacus; experts exhibit astonishing calculation abilities. Over 3 years, 204 elementary-school students (age-range at outset: 5-7 YO) participated in a randomized, controlled trial to test whether MA expertise (a) can be acquired in standard classroom settings; (b) improves students' mathematic...

The aim of this research was to determine the ability level of paralinguistic production and comprehension in adults with intellectual disability (ID) with regard to the level of their intellectual functioning and presence of co-morbid psychiatric conditions or dual diagnosis (DD). The sample consisted of 120 participants of both genders, ranging in age between 20 and 56 years (M=31.82, SD=8.70...

This study aimed to investigate the orientation dependence effect and the role of visuospatial abilities in mental representations derived from spatial descriptions. The analysis focused on how the orientation effect and the involvement of visuospatial abilities change when survey and route descriptions are used, and the initial and main orientation of an imaginary tour. In Experiment 1, 48 par...

Walker's comprehensive review of claims of gender difference and gender bias in moral cognition concluded 1) that gender explains a negligible amount of the variability in moral reasoning development, 2) that accumulated evidence does not support claims of gender polarity in moral orientations (i.e., an ethic of care and an ethic of justice), and 3) that future research should focus on the rang...

A frequently reported finding is that general mental ability (GMA) is the best single psychological predictor of job performance. Furthermore, specific abilities often add little incremental validity beyond GMA, suggesting that they are not useful for predicting job performance criteria once general intelligence is accounted for. We review these findings and their historical background, along w...

Competence to stand trial is necessary for a defendant in criminal adjudication. Recent estimates indicate that between 50,000 and 60,000 defendants in the United States raise the question of competence each year, with approximately 20 percent found incompetent to stand trial (IST). Most of these defendants are committed to an inpatient facility for competence restoration. Although psychopharma...

In a series of experiments, young children who were disoriented in a novel environment reoriented themselves in accord with the large-scale shape of the environment but not in accord with nongeometric properties of the environment such as the color of a wall, the patterning on a box, or the categorical identity of an object. Because children's failure to reorient by nongeometric information can...

Social functioning is as an important outcome in studies of people with schizophrenia. Most measures of social function include a person's ability to manage everyday activities as well as their abilities to engage in leisure and occupational activities. The Personal Social Performance (PSP) scale assesses functioning across four dimensions (socially useful activities, personal and social relati...
